Embodiment 1

[0037] A preparation method of cream base paper, the method comprises the following steps:

[0038] (1) 3 packs of softwood pulp imported from North America (air-dry weight 230kg / pack), 2 packs of hardwood pulp imported from Brazil (air-dry weight 250kg / pack), and 4 packs of softwood pulp imported from North America (air-dry weight 230kg / pack) and imported from Brazil 1 bag of hardwood pulp (air-dry weight 250kg / bag) is put into the long-fiber pulper by feeding at intervals, adding 0.25kg / t CMC, adding white water to a concentration of 6.5ωt%, and then crushing. The crushing time is 12 minutes, and then Pumped into the long fiber pulp pool;

[0039] (2) 5 bags of hardwood pulp imported from Brazil (air-dry weight 250kg / bag) are put into a short fiber pulper, add 0.28kg / t CMC, add white water to a concentration of 6.5ωt%, and then disintegrate. The disintegration time is 10 minutes. Afterwards, it is pumped into the pulp tank before the staple fiber tap;

Abstract

The invention relates to a preparation method of cream base paper, which comprises the following steps: (1) decomposing paper pulp, and pumping the decomposed paper pulp into a long-fiber pre-beating pulp pool; (2) pumping the pulp into a mixed pulp tank, and then adding a softening agent; (3) slightly treating the fibers through a fine pulping machine, and feeding the treated fibers into a pulping pool; (4) adding a wet strength agent, conducting concentrating and diluting, and preparing to condct pump to a paper machine; (5) diluting the pulp by a slushing pump, and then forming, squeezing and drying the pulp in a paper machine; and (6) wrinkling the dried paper by a wrinkling knife, winding the paper into initial roll raw paper by a paper winding cylinder, and rewinding and slitting the initial roll raw paper into the cream base paper. Compared with the prior art, specific high-quality imported pulp is selected to be mixed according to a specific proportion, a low-beating-degree beating mode is adopted, a specific amount of chemicals with excellent safety and functionality are added, and a nano ceramic wrinkling knife is selected to produce the cream base paper meeting the requirements of customers on cream spraying.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for preparing cream base paper. Background technique [0002] With the continuous improvement of people's living standards, people pay more and more attention to the quality of life. The demand for household paper used as fast moving consumer goods is also gradually increasing, especially for facial tissues that are frequently used to wipe the face, mouth, nose, etc. [0003] The cream paper endows the paper with softness, smoothness and moisture retention far beyond ordinary facial paper. Its biggest difference from ordinary facial paper is that it adds moisturizing cream ingredients, which greatly improves the softness, slipperiness and moisturizing degree of the paper. The cream paper has silk-like smoothness and cotton-like softness, which not only has little irritation to sensitive skin, but also has moisturizing effect. These all bring consumers an experience that ord...
